Design/Logic Flaw

The fspin implementation in the Linux kernel before 4.0.5 does not ensure the internal consistency of a certain list data structure, which allows local users to cause a denial of service system crash by leveraging user-namespace root access for an MNTDETACH umount2 system call, related to...

Design/Logic Flaw

fs/namespace.c in the Linux kernel before 4.0.2 processes MNTDETACH umount2 system calls without verifying that the MNTLOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user...

fs/namespace.c in the Linux kernel before 4.0.2 processes MNTDETACH umount2 system calls without verifying that the MNTLOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user...

UBUNTU-CVE-2015-4176

fs/namespace.c in the Linux kernel before 4.0.2 does not properly support mount connectivity, which allows local users to read arbitrary files by leveraging user-namespace root access for deletion of a file or directory...

UBUNTU-CVE-2015-4177

The collectmounts function in fs/namespace.c in the Linux kernel before 4.0.5 does not properly consider that it may execute after a path has been unmounted, which allows local users to cause a denial of service system crash by leveraging user-namespace root access for an MNTDETACH umount2 system...

CVE-2016-1576

CVE-2016-1576 concerns the Linux kernel overlayfs. The overlayfs implementation up to version 4.5.2 does not properly restrict the mount namespace, enabling a local user to gain privileges by mounting an overlay filesystem on top of a FUSE filesystem and then executing a crafted setuid program. T...

CVE-2016-2853

CVE-2016-2853 – Linux kernel aufs Privilege Escalation : The vulnerability arises in the aufs module (Linux kernel 3.x/4.x) where mount namespace restrictions are insufficient. A local attacker can mount an aufs filesystem atop a FUSE filesystem and, by executing a crafted setuid program, escalat...
